Subject: [nfsv4] open(O_CREAT) returns EEXISTS on symbolic link created on another system until stat()ed
Date: Thu, 29 Mar 2012 16:28:42 +0000 (UTC)	[thread overview]
Message-ID: <loom.20120329T182500-467@post.gmane.org> (raw)

I filed a bug here: https://bugzilla.redhat.com/show_bug.cgi?id=808112

Description of problem:

client A:
touch blah
ln -s blah blahlink

client B:
open("blahlink", O_RDONLY|O_CREAT, 0666) = -1 EEXIST (File exists)
$ ls -l blahlink
lrwxrwxrwx. 1 orion cora 4 Mar 29 09:30 blahlink -> blah
open("blahlink", O_RDONLY|O_CREAT, 0666) = 3

Removing and recreating the link on client A restores the problem.

earth:/export/home/orion on /home/orion type nfs
(rw,noatime,intr,rsize=32768,wsize=32768,actimeo=1,sloppy,vers=4)

I thought this might be the same as the recent stat() issue brought up in
relation to viminfo files, but it fails on kernels with that fix.

I can't reproduce on RHEL5 kernel 2.6.18-308.1.1.el5, but I can on
2.6.42.9-2.fc15.x86_64 through 3.4.0-0.rc0.git1.2.fc18.x86_64.
